The right tools for the right job

It should be noted that the main tools used in wood carving are gouges, chisels, knives and riffers. But that say that it is also nice to have a fill power tools on hand to speed up the operation. Called "roughing out" stage. This can include but are not necessary to have but are nice to use to speed the operation. These are the chop saw to cut materials to rough length, the scroll or saber saw if curves are involved, and for those really large projects "the chain saw."

Gouges:

There are basically three groups. A gouge is basically a chisel with a curved cutting edge.

Shaft - Straight, Curved,Spoon, Backbent
width - the width of the cutting edge
Sweep - the curve on the cutting edge, from almost flat to U shaped (numbers 3 - 9)

No - one is expected to own all the possible permutations, so start with an all - purpose selection. Example
straight 3/4 inch number 4, Straight 1 1/2 inch no 5 and a Curved 3/8 inch number 8.

Knives:  

A curved blade is long and pointed is long and pointed enough to get into tight corners, and the shape of the lets you make a real fist round it so you put a lot of power into the cuts. Some f the Japanese knives look similar to the Swedish Sloyd, but not as chunky. These cold possibly be used by the ladies perhaps.

Beware.... some tool suppliers often put "Chip Carving Knives" in with other carving tools. The chip carving knives have flat blades and are used and suitable for wood chip carving (engraving flat surfaces).

Rifflers and Rasps

A riffer is a small curved file with various shapes at each end, designed for smoothing out small curved places. The most useful shapes are the Ratstail and ski shapes.

Rasps are similar but much bigger, for quick basic shaping of flat or convex surfaces.

Power tools
Angle grinder is useful for scooping out if an Arbortech wood cutter blade is used. Make sure you get the grinder that is strong enough but light enough to hold in one hand. It should be noted that this can be more violent the the chainsaw. The instructions say keep both hands on your tool and THEY ARE NOT KIDDING.

Dremel 300 or ohers small multi purpose rotary tools:
The Dremel 300 variable speed rotary tool is very versatile and is small enough to hold like a pen. It lets you set the speed to control how much or how little wood your diamond cutter removes from the smallest recesses. Make sure to have a good selection of small drill bits and sanding disk, drums. You will need the drill bits for pierce carvings.

Other items to have on hand. A hand plane - to bring the stock down in thickness. If you have power planner - this works to.

For the large carving (the big 3 D ones that stand 6 ft tall or larger)
Chainsaw - This is noisy, oil splattered and potentially violent assault, but with lots of practice you can do your early roughing out in hours rather than days. Gasoline chainsaws are more powerful than electric but with the combustion 2 - stroke exhaust fumes make them unsuitable to use indoors.

Sculpture or Carving

There are two broad camps. There are those from an art background who include wood as one of their mediums, them there are those from the woodworking background who include "Carving in the round" as one of their activities. Sculpture implies starting with a creative design, which is then turned into 3D reality by whatever means. Carving more implies an activity, the end product of which may or may not be particularly artistic. In carving...What the heck? its just semantics.

Techniques of Relief Wood Carving
The quick and dirty version of carving


One must begin with a design, be it already made or drawn. Here above is a Celtic circle pattern that may have been caved in the time of the Anglo Saxons. This is only to show what is required for a pattern although complex, if one takes the different elements, one will see that it can be simple. Although you may be new at this craft I Charles suggest to begin with a simpler project. Patterns and designs can be found on the chat room and http://norsedesigns.blogspot.com

After choosing a pattern or drawing your own, a bench and SHARPEN chisels and gouges are required to do the carving. Please do not use the dollar special chisels and gouges as these have a tendency to not hold their sharpness. You will need a few gouges to begin with, and can if interested in purchasing more as you become accustom to the craft. In during sharping, please use a wet stone, and use a slide way action to sharpen the gouge, than use a leather belt and with a side action to clean any burrs from the blade. It is very important to keep your gouges sharp. If you feel drag on the gouge,and a rough texture appears on the wood stock it is time to sharpen the gouge. IT IS IMPORTANT TO MASTER THIS TECHNIQUE in sharping. A dull gouge or chisel can damage the project or worse yet you may be injured in using a dull tool. In the future there will be a post in this section on how to sharpen a gouge or chisel.

The next step, is what am I going to carve it from. The best materials to learn in the carving technique is basswood or clear white pine. Make sure that the grain is straight, and try to avoid knots. You do not want figure wood to start off with. Lady Christiana begun with birch, although hard it is a stable wood that has no pitch pockets. If one hits a pitch pocket, and depending on the depth of the pocket, the carving elements will have to be deepen to remove the pitch pocket. Other woods that respond nicely to carving, and have stable grain but can be expensive is tulip wood, and maple - these woods are hard and as such should not be used by a first timer to this art.

In setting up it is recommended to have a stable, lit area - use adjustable spot full spectrum lighting and set to one side to cast a shadow on the relief carving. This will indicate where future work will be needed and cleanup of the elements. The light should be adjustable to do this, and if at possible it is nice to work with natural light. Clamps for clamping the stock will be required as one carves. Here shown is one of Charles Benches for woodcarving, with a students piece been prepared for relief carving. Seen here the stock is clamped and the gouges are laid out already sharpen to use.


On another carving bench is Charles carving a Norseman on a horse. The beginning of preparing the carving to receive its carving elements. Note the position of the gouge as he begins to do the set.


Techniques in Relief Carving: Note: do not expect your first piece to turn out like a professional old world wood carver's piece, as this takes years to learn, knowledge of wood species and direction of wood grain, and of course the ability of sharp gouges. This takes time and experience to learn this old craft.
The  pattern of carving, which can be three dimensional figures, to relief carving must start out as a pattern either from designs or from your own imagination. The pattern must be transfer to wood stock before carving can be done. One must prepare the stop before one can carve. Setting down is a two stage process: first involving the stop cut, which is where the chisel is used to make the stop, and than with a gouge: a woodcarving with a radius curve is used to remove the unwanted wood from the carving as shown in the above photo above. This process is to be repeated until the required preferred depth of the ground is reached - Ground shown in photo above: ground is how far the background is below the surface on a relief carving. With some designs besides taking down the exterior edge of the pattern, some of the interior design may require it be taken down in the same manner - photo below shows this technique.


Carving elements: As the carving progresses one will come to the area of where the carving overlaps itself where a stop is preformed, and bringing down the level of the carving about half way to the ground, so that the carvings look like it flows through the upper part of the element as shown in the above photo.

Round the upper edge of the element within the carving is the ext step. Once the radius is carved, a cut back on the bottom edge of the element is required, and clean up of the carving so that there is no chips or slivers. Running your hand over the carving is required to assure there are no slivers and or no rough spots. (heaven forbid that one picks up a sliver so be careful in during this step) and if it is clean to the touch, the carving is complete. The carving is now ready for a suitable finish at this time.

Tip 1: Keep your gouges sharp
Tip 2: Make sure your work piece is well clamp to prevent movement of the piece while working on it
Tip 3: Transfer your design to wood (This can be done prior to step 2)
Optional -  If the wood is dry - use mineral oil to make the wood less likely to split. Do this before gluing the design (on a piece of paper) to the stock.
Tip 4: Keep your gouges sharp
Tip 5: Set your stops and use gouges to attain the ground
Tip 6: Sharpen your gouges
Tip 7: Set your elements
Tip 8: Sharpen your gouges
Tip 9: do any relief grounding and stop cuts when it comes to two different grounds
Tip 10 Sharpe  your gouges
Tip 11:  Cut back on the bottom edge of the carving details
Tip 12: Sharpen your gouges
Tip 13: rub your hand over the carving surface checking for imperfections
Tip 14: Sharpen your gouges
Tip 15: clean up of the carving surface
Tip 16: Repeat tips 14 and 15 to completed
Tip17: finish with a good quality finish
You are now complete - time to do another one
